Desmond, Philadelphia, Pa., assigner to Container Corporation ofAmerica, Chicago, Ill., a corporation of Delaware Filed Dec. 12, 1960,Ser. No. 75,275 1 Claim. (Ci. 4o-62) This invention relates to visualaids of the type commonly used for education or amusement, land moreparticularly to a slide view device.

The invention comprehends an improved construction 'and arrangement foraslide view device of the type in which a card is slidably mounted in aguide for manipulation to provide alternating sets of printed matter,such as lines orf printing, pictures, or blank areas, which may beviewed through spaced slots in the gnide.

It is an yobject of the invention to provide an improved rslide view`device lof simple design and construction which [can be easily formedfrom a single blank of sheet material and which can be readilyassembled.

A more specific object of the invention is the provision of a slide View`device comprising la card, having alternately spaced areas which areprinted or blank, which is slidalbly mounted in a guide, havingalternately spaced slots Itor cooperation with the areas on the card.-These and other objects of 'the invention will be apparent from anexamination of the following description and `drawings wherein:

FIGURE 1 is la fragmentary front elevational view of a slide view deviceembodying features of the invention;

FIGURE 2 is a rear ielevational view of the structure illustrated inFIGURE 1;

FIGURE 3 is a transverse sectional View taken on line 3 3 of FIGURE 2;

FIGURE 4 is a detailed front elevational view of a portion of thestructure of FIGURE l, illustrating the relationship between the spacedareas on both the slide and guide members of the device; and

FIGURE 5 is a top plane view fof a blank of sheet material from whichthe device of the other views is formed.

It will be understood that certain elements have been intentionallyomitted from certain views where they alleV illustrated to betteradvantage in other views.

Referring now to the `drawings for a better understanding of theinvention, and particularly to FIGURE 5, it will be seen that the devicecomprises a slide member, indicated generally lat 10, adapted to beslidably mounted within a guide member, indicated generally at 12. Theentire device can be formed from a blank 14 of a suitable sheet materialsuch as foldable paperboard. As seen in FIGURE 5 the slide and guidemembers 10 and 12, respectively, are separated from each other by aperforated line 16 in the blank 14, so that in 'assembling the devicethe members and 12 are separated from each other to divide blank 14 intoseparate parts.

Still referring to FIGURE 5, it will be seen that slide 1t) is agenerally flat H-shaped panel having at the top and bottom ends thereofpairs of end portions 20 which are of greater width than the centerportion 22 so as to project outwardly therefrom and define therewith apair orf recesses 24 on opposite sides of the slide. At one end theslide may be provided with an opening 26 to facilitate in the operation`of the device in a manner explained hereinafter.

As best seen in FIGURES l and 3 slide 10 is provided with a plurality ofspaced lines 28 'of printed material. The spacing of the lines 'ofprinted material from each other will be discussed in connection withthe guide member.

3,106,029 Patented Oct. 8, 1963 The guide 12 includes a at generallyrectangular main or center panel 30 having hingedly attached to oppositesides thereof, along longitudinal score lines 32, a pair of slide memberreceiving anges 34. Each 'of the ilanges 34 includes a relatively narrowelongated rectangular retaining strip 36 which extends the entire lengthlof the guide panel 30. Projecting outwardly from a medial portion ofeach retaining strip 36 is a glue flap 38 which is also relativelynarrow and elongated but which does not extend for the entire length ofthe retaining strip. rllhe length lof the glue ilap is less than lchevlength of the center portion 22 of the slide for a reason which will bedescribed later in connection with the operation of fthe device.

The center panel 30 of the guide member, as best seen in FIGURES 1 and4, is provided with a series of alternately spaced lines of printedmaterial 40 between which lare located la series off alternately spacedslots 42. For illustrative purposes the material 40 is shown as seriesof the letter B. It will be seen that 'the spacing between the lines ofprinted material on the guide panel 30 correspond to lthespacing of thelines on the slide member 10 and also to the spacing of the slot-s 42,so that by shifting the slide within the guide rto alternate positionsdifferent sets olf printed areas illustrated by the alternate series ofthe letters A and C, can be viewed through the slots in fthe guidemember. The guide member may Ialso be provided with an yopening 44 tofacilitate Ioperation lof the device in cooperation with the opening 26in the slide member.

To assemble the device the slide member 10 is separated rom the guidemember 12 of the blank 14 by dividing the blank along perforated liney16. The slide is then placed with its tforward surface, having theprinted areas, in juxtaposition with the rear surface of the centerpanel of the guide member. It will be seen that the width of the slidemember 'at its widest part is approximately equal to the width of thecenter panel 30 of the guide member.

After the slide member has been placed on the guide member the retainingflanges 34 are folded over with the glue flaps 38 radhesively secured tothe back of the guide center panel 30 and with fthe end portions 20 ofthe slide tucked under the ends of the retaining strips 36 of the guideiianges 34. Thus, the slide is r,free to move lengthwise within fthe`guide member, and the length or extent lof the movement is limited bythe relationship of the 'glue flaps to the end portions of the slide. Aspreviously stated, the `distance between the end portions iof the slideis greater than the over-all length of lthe glue flap of the guide, sothat the inner edges olf the end portions of the slide are abuttablyengageable alternately with 'the opposite end edges of the glue flaps,and the spacing of the printed material is so arranged that when theslide is in its upper-most position one set of printed areas is visiblethrough the slots from the yfront side of the device and when the slideis in i-ts other position the other set of printed areas is visiblethrough the slots of the guide member.

Although in order to illustrate this invention the device has beenrepresented Ias having -two sets of printed areas on the guide memberwhich could be alternated by placing the slide in either one of twopositions relative to the guide, it will be understood that more thantwo positions could be provided. Also, instead of providing twodifferent sets of printed `areas on the slide member there could beprovided lone set orf printed areas alternated with blank Iareas.

In all of the various arrangements for which this device can be adaptedthe real essence of the invention lies in the novel arrangement wherebythe device can be formed from a single blank of sheet material andwherein the glue flaps serve as a novel retaining means for the slidecard. Because the slide can be easily slipped in and out of the guidemember it is also possible to use the guide member with ra lplurality ofdifferent types of slide members having diierent printed legendsthereon.
